Specification of Letters Patent.

Patented Oct. 10, 1911.

Application filed October 20, 1910. Serial No. 588,017.

To all whom it may concern:

Be it known that I, EPPA H. RYoN, a citizen of the United States, residing at /Valtham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Holding and Releasing Devices for Bobbins in Magazines of VVeft-Replenishing Looms, of which the following is a specification.

My invention relates to a magazine for weft replenishing looms, and to that class of magazines which have two or more vertically extending guide-ways or compartments for series of superimposed bobbins or filling carriers, which drop down by gravity in a guide-way or compartment, and are retained therein by a device of mechanism at the lower end thereof, which device or mechanism is operated, at the desired time, to release the lowest bobbin, and allow it to drop down to the discharging end of the magazine, preparatory to being transferred into the active shuttle, and to hold the bobbins above said lowest bobbin, in their compartment, during the transfer of the lowest bobbin.

My invention particularly relates to a device or mechanism for holding the bobbins in their compartments in the magazine, and for releasing the lowest bobbin, and for retaining the other bobbins in the compartment.

The object of my invention is to provide a bobbin holding and releasing device of improved construction, which preferably consists of two movable devices or bars, which will engage and hold the head of a bobbin, and also engage and hold the tip of a bobbin.

In my improvements I preferably have for the holding and releasing device for the lowest bobbin in a compartment, two movable, preferably sliding members or bars, suitably guided at each end, to have a longitudinal movement at the desired time, in opposite directions. The sliding members are each preferably provided with two extensions, one for the head, and one for the tip of a bobbin. Said extensions are adapted to be alternately moved with the sliding members into and out of the path of the head, and of the tip of a bobbin, to cause, on the movement of said sliding members, in one direction, the lowest bobbin to have its preliminary movement, preparatory to being conveyed to a position under the transferrer, and the reverse movement of said sliding members, will release the lowest bobbin and cause the bobbins in the compartment above the lowest bobbin to be retained in their position in the compartment.

My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

I have only shown in the drawings a detached portion of a weft replenishing loom, and a magazine of the type shown and described in U. S. Letters Patent, No. 933,492, and particularly shown and described in my pending application, Serial No. 581,387, with my improvements combined therewith, suhicient to enable those skilled in the art to understand the construction and opera tion thereof.

Referring to the drawings :--Figure 1 is an inner end view of a magazine of the type above referred to, and the bobbin holding and releasing mechanism of my improved construction. Fig. 2 is a sect-ion, on line 2, 2, Fig. 1, looking in the direction of arrow a, same figure. Fig. 3 is a plan view of the bobbin support, detached, looking in the direction of arrow 6, Fig. 2; Fig. 4: shows the bobbin support, shown in Fig. 1, detached, and in its opposite position, and, Fig. 5 is a plan View of the bobbin support, looking in the direction of arrow 0, Fig. 4; the bobbin resting therein is shown by broken lines.

In the accompanying drawings, 1 is a stand secured to the breast beam of the loom, not shown, which carries the inner end 2 of the magazine, having in this instance four guide-Ways or compartments 2, for the heads 3 of the bobbins 3. The outer end 4:, Fig. 2, of the magazine, has guideways or compartments 4: for the tips 3 of the bobbins 3. The inner end 2, and the outer end 4: of the magazine are preferably connected by transverse rods, not shown, in the ordinary Way, and each end has a dis charge opening 2 and 4.", respectively for the bobbins 3. The bobbins 3 are supported and drop down by gravity in the magazine.

5 is the transferrer arm, mounted on studs 6, see Fig. l, on the stand 1, and is adapted to engage the bobbin with its engaging end 5. The downwardly extending arm 5 is adapted to carry a dagger or latch, not shown, in the usual way.

At the inner end of the magazine are suitably guided the upright bars 6, which are provided at their upper ends with weighted hooks 7 which are adapted, on the downward movement of a bar 6, to engage and rock a lever 8, which has its hub 8 secured on a rock shaft 9. The outer end of the shaft 9 has secured thereon the hub 10 of a lever 10. A stud 11 enters a hole in a block 12, which is adapted to loosely slide in anelongated opening 13 in a lever 13, which lever has its hub 13" loosely mounted on a stud 14. A helically coiled expansion spring 15 acts to hold and lock the levers 13 and 10 in their upper and lower position. Through intermediate connections, not shown, from the lever 13 to the dagger on the transferrer arm 5", said dagger will be raised into the path of and be engaged by the hunter on the lay, not shown, to transfer the bobbin being released from a compartment.

' The bearings 2 on the magazine have loosely mounted therein a longitudinally moving rod 16. The end of the rod 16 has a collar 17 secured thereon, which is provided with an annular groove 17 into which extends a side extension 18 on an arm of an angle lever 18. r The angle lever 18 has its hub 18 loosely mounted on a stud 19 carried on a stand 20. The other arm of the angle lever 18 is connected, through intermediate connections, not shown, to the drop shuttle box mechanism, not shown, on the opposite end of the loo-1n. The raising and lowering of the drop shuttle boxes will communicate a reciprocating movement to the rod 16, to cause it to be moved longitudinally according to the movement of the shuttle boxes, and will cause said rod to have four differentpositions longitudinally. Extending upwardly from the weft replenishing mechanism, not shown, on the loom, is a rod 21, which has its upper end pivotally connected to a pin 22 on a lever 23, which lever has itshub loosely mounted on the rod 16, and is prevented from having a longitudinal movement on said rod by the two lugs or bearings 2". The lever 23 is provided with lugs 23", which loosely receive the spring actuated bolt 24:, which, through the action of the h'elically coiled expansion spring 25 at the horizontal position of the lever 23,

bears against the foot 2 of the bearings 2",

to prevent the lever from moving downward, unless through the action of the weft replenishing mechanism, not shown. The longitudinally moving rod 16' has secured thereon, to move longitudinally therewith,

. the hub 26 on the operating fingers 26.

The side extension 26 extends loosely into a notch or recess in the lever 23. The up and down movement of the lever 23 will,

through the extension 26", communicate an up and down movement to the fingers 26, and through the engagement of the fingers 26 with an extension 6' on the vertically moving bars 6, move up or down the selected bar 6 to release a bobbin.

All of the above mentioned parts, excepting the particular construction of the bars 6, may be of any usual and well known construction, and are particularly shown and described in U. S. Letters Patent No. 933,492, and in the application, Serial No. 581,387, above referred to.

I will now describe my improvements, which as above stated, relate to the holding and releasing device for.the bobbins in the magazine.

Combined with the inner end 2, and the outer end 41 of the magazine, near the lower discharging end thereof, are movable bobbin holders or sunports, which in this instance consists of two members or bars27 and 28, preferably made of sheet metal, which extend transversely across the magazine at the lower end of each compartment of the magazine, in-a position parallel to the lowest bobbin in each compartment of the magazine. The members or bars 27 and 28 are loosely guided in suitable slots at the outer and inner end of the magazine, to have a longitudinal sliding movement. The inner ends of the bars 27 and 28 have in this instance the enlarged portions 27 and 28, which are provided with curved or cam shaped slots 27 and 28, which at their upper parts in this instance extend outwardly or diverge from each other, as shown in Figs. 2 and 4. The curved slots 27 and 28 are adapted to receive a pin 6 at the lower forked end 6 of the vertically moving bar 6. A bar 6 on its up and down movement, is adapted to communicate a longitudinal sliding movement to the pair of supporting bars 27 and 28, to which it is connected, in such a manner that said bars 27 and 28 are moved in opposite directions, or in a direction away from each other. The bar 27 has on its upper inner edge a side extension 27, which on its movement in one direction extends under the head of the lowest bobbin in the compartment, and acts to retain the head of the bobbin. The bar 28 has on its upper inner edge a side extension 28*, which extends under the tip of the lowest bobbin, and acts to retain the tip of the bobbin in position, on the normal operation of the loom, as shown in Fig. 2. The bar 27 has a side extension 27 b on its lower inner edge, and the bar 28 has a side extension 28 on its lower inner edge.

When a vertically moving bar 6' is moved upwardly, as shown in Fig. 4, the two slidtudinal movement in opposite directions, or

. in a direction away from each other, and the lowest bobbin is released by the disengagement of the side extensions 27 a and 28 therewith, and then said bobbin drops until its head rests upon the side extension 28 on the lower edge of the bar 28, and until its tip rests upon the side extension 27 on the lower edge of the bar 27. When the bar 6 moves downwardly again, the sliding members 27 and 28 are again moved longitudinally in opposite directions and the lowest bobbin, which has had its preliminary movement, will be dropped to the discharging end of the magazine, the remaining bobbins in the compartment are held by the upper extensions 27 and 28* on the sliding bars 27 and 28, respectively, as shown in Fig. 2, and this operation is repeated on the selection of a bobbin from each compartment.

The advantages of my improvements will be readily appreciated by those skilled in the art. By means of the two members, forming the holding and releasing mechanism for the bobbins in each compartment, said members preferably comprising sliding bars which are adapted to be positively moved longitudinally in opposite directions, the bobbins are held or supported in their compartments, and on the release of the lowest bobbin, preparatory to being transferred, the bobbin next above the lowest bobbin is held and supported, to retain the other bobbins in the compartment.

It will be understood that the details of construction of my improvements may be varied if desired.

I have shown in the drawings my holding and releasing mechanism. for the bobbins combined with a particular type of magazine for weft replenishing looms, but it will be understood that they may be combined with any other type of magazine for weft re plenishing looms.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a magazine of the class described, a guide for superposed bobbins, supports for said bobbins, said supports comprising slides having thereon lips or extensions for the ends of the bobbins, and means to move said supports longitudinally.

2. In a magazine of the class described, a guide for superposed bobbins, supports for said bobbins, comprising slides having thereon lips or extensions for the ends of the bobbins, and means to move said slides longitudinally in opposite directions.

8. In a magazine of the class described, a guide for superposed bobbins, supports for said bobbins, said supports comprising slides having lips or extensions thereon for the ends of the bobbins, and having cam slots therein for a pin to cooperate with said slots, and said pin, and means to operate said pin to cause said slides to move longitudinally.

4. In a magazine for bobbins or filling carriers, guides for superposed bobbins, supports for said bobbins, said supports including a member to support the butt end of the bobbins, and a second member to support the tip end of the bobbins, and means to automatically move said members simultaneously in opposite directions.

5. In a magazine for bobbins or filling carriers, guides for superposed bobbins, supports for said bobbins, said supports including a member to support the butt end of the bobbins, and a second member to support the tip end of the bobbins, said members adapted to be moved in opposite direct-ions, and means to automatically move said members.
